**Which option is best depends on the content you’re tagging.** If your posts are broad guides, options 1-3 are good. If focused on banking, option 2 is fitting. For technical deep dives, choose option 5. Option 4 is ideal if you’re addressing multiple services. I’d recommend starting with either **Option 1 or Option 2** and adjusting slightly based on the content of your associated posts.
